count_calls.m function count_calls persistent ccount if (~exist('ccount')) ccount = 0; end; ccount = ccount + 1; printf('Function has been called %d times\n',ccount);
We now call the function several times:
--> for i=1:10; count_calls; end Function has been called 1 times Function has been called 2 times Function has been called 3 times Function has been called 4 times Function has been called 5 times Function has been called 6 times Function has been called 7 times Function has been called 8 times Function has been called 9 times Function has been called 10 times
